Application iiled February 6 1907. Serial No. 356.117.

- Be it'known that I, LOUIS ARsENE 'Di'isr, a subject of the Kin of Great Britain,residing at the city and District of Montreal, in the Province of Que ec, Canada, have invented certain new and useful Improvements in Excavator-Scrapers; and I do hereby deexact description of the invention,,su ch as will enable others skilled in the art to which it appertains to make and use the same.

, ings-l) of the bucket.

the bucket the My invention relatesto'excavator scrapers; the object of myinventionis to provide a scraper adapted for use in connection with an ordinary form of excavator bucket for the purpose the bucket is cleaned every time it is opened or closed; and, my invention consists of the construction, combination and arrangement of parts, herein illustrated, described and claimed. I

In the accompany ng drawings, forming part of this application, I haveillustrated one form of embodiment of this invention,'in which drawings similar reference characters designate corresponding parts, and in which: Figure 1 is a side elevation, partly in section, showing the application of my invention toa V '2 is a horizontal section through the scraper actuating links, showing the scraper in plan.

Referring to the drawings, A designates a beam having a shoe B on its lower end, pro-. vided with bolts C. The castings D, to which are secured the leaves E of the bucket, are pivotally disposed on the bolts'O.. The.

links F are adapted to actuate the bucket into the position shown in dotted lines in Fig. 1. All of this construction may'beof any connnon and well known form. The

shoe B is provided with brackets 1 carrying 2, to which are connected the links 3, the lower ends as at 4 to the arms the pintles or pins the upper ends of of the links being pivoted 5, which arms are pivoted The arms 5 areprovided with sockets 7, adapted to receive the ends of the yokes S, which yokes extend to and are adapted to scrape the inner walls of the leaves IE. The ends of the yo'ires S are adjustably the insertible members 9, which may be bolts orset-screws.

The bucket being in the position shown in of scraping from the leaves ofmaterial being dug, so thatas at 6 to the castheld in the sockets 7 by means of.

full lines in Fig. 1, the ypkess will rest acent the upper edges of the leaves E. The bucket being actuated to the position shown in dotted lines in Fig. 1., the movement of the yokes 8 will be limited against the same as the yokes move with the leaves they will travel over the inner face of the leaves to clean the same when the leaves are actuated to the dotted line position. This movement closed, so that the yokes travel over the leaves twicein the operation of opening and closing. The-link connections 3 between the arms 5 and the pins 2 force the yoke 8 to travel through a muchshorter arc than that traversed by the bucket leaves upon which they operate. their movements, the yokes 8 scrape the leaves over which they pass thoroughly both as the bucket opens and closes.

.Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, isz

' 1. In combination with an excavator bucket having a plurality of leaves, means is operated.

2. In combination with an excavator bucket comprising a plurality of leaves hav- .and adapted to be moved over the leaves of .the bucket when they are opened or closed.

3. In-combination with a bucket having pivoted sides and means for swinging the sides on their pivots, arms pivoted to the sides. of the bucket, scrapers carried by the arms, and means for limiting the movement of the arms when the sides are moved.

4. In combination with a bucket having pivoted sides and means for swinging the sides ,on their pivots, arms pivoted to the sides of the bucket, yoke-shaped scrapers carried by the arms, and means for limiting the movement of the arms when the sides are moved. v

5. In combination with a bucket havingpivoted sides and means for swinging the sides on their pivots, arms pivoted to the sides of the bucket and provided with sock.- ets, yoke-shaped scrapers having their ends disposed in the sockets, means "to r adjustably securing the ends in the sockets, and means length of movement as the leaves E, so that,

of the yokes is reversed when the bucket is Due to this limitation of connected with each of the leaves for scraping a the inner wall of the bucket when the bucket sides on their pivots, arms pivoted to thesides of the bucket and provided With sockets, yoke-shaped scrapers having their ends disposed in the sockets, insertible members disposed through the sockets and the ends of the yo'kes, and means for limiting the movement of the arms when the sides are moved.

7. In combination with a bucket having pivoted sides and means for swinging the sides on their pivots, arms pivoted to the sides of the bucket,- scrapers carried by the arms, links pivoted at one end torthe arms, and a fixed'pivotal support for the opposite ends of the links,

' 8. In an excavator, 'the combination of a beam having a shoe on its lower end provided with lugs, a bucket having its sides pivoted to the shoe, means for swinging the sides of the buckc 1;, arms pivoted to" the sides of the bucket, scrapers carried by the arms, and links having their opposite ends pivoted respectively to the arms and the lugs on said shoe.

, 9. In combination with a-multipart excavator bucket, means for scraping the inner Wall of. the bucket when its parts are moved.

1( In combination with a multileaved excavator bucket, a scraper carried by each of the leaves, and arranged to operate by the movement of the leaves.

11. In combination with a multileaved eX- cavator bucket, a scraper carried by each of the leaves, and each arranged to be independently operated by the movement of its corresponding leaf.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
